HELIX M FOUR DSP - 4 Channel Amplifier | 10ch DSP

The M FOUR DSP is more than “just” another four-channel amplifier – rather, despite its small dimensions, you are dealing with a powerful control center that has not less than a total of ten processed DSP channels. In addition, the amplifier delivers plentiful output power with generously 100 Watts RMS per channel into both 4 Ohms and 2 Ohms load.

Finally, its awesome price-performance ratio in combination with the fantastic feature set will ensure bright eyes.

Tonally absolutely HELIX!

Compromises in terms of sound quality have no place in a HELIX product – and that's why the M FOUR DSP is equipped with all the finesse for the perfect sound. 

Maximum flexibility

Even the internal amplifier section of the M FOUR DSP is extremely variable – it can either be operated in 4-channel mode or, thanks to its bridging capability, can also be configured as a 3-channel or even 2-channel amplifier.

Virtual Channel Processing – that´s how signal routing works today

Many DSP channels need to be managed and configured properly – so there was no question that the M FOUR DSP is also equipped with Audiotec Fischer's innovative virtual channel processing.

The plus in speed – thanks to ACO

Faster is better – the particularly powerful 32 Bit ACO platform takes over all control tasks and ensures significantly more speed, especially for data communication with the DSP PC-Tool software but also for the lightning-fast switching between up to ten sound setups. 

Compact, cool and absolutely practical

Despite its vast range of functions and huge output power the M FOUR DSP presents itself in the same classic, compact HELIX design with distinctive lines like a HELIX M FOUR or M ONE. Thanks to its Class D amplifier technology, it keeps a "cool head" even at full power.
